I have an Angular 2 site which is not completely working in Firefox. The problem is that it doesn't recognize the event that I pass into my typescript function. The event is a mouse click and the function is a mouse click event handler.

What is the proper way to get the click event in a click event handler in Firefox running an angular site with typescript? If I'm doing it right in the above code, what could be causing it to say it doesn't recognize the event variable?
